Platform and software requirements: While it should work on any modern browser on any modern OS, we did our testing on Chrome running on OSX. At the least, we recommend using Chrome on your OS of choice.

Parts of the prototype which are shallow: The interface is high-fidelity in look and high-fidelity in feel, but low-fidelity in both breadth and depth. We've focused on the interface design itself, and so what you see is what we would envision the final product looking like. Functionality is "canned," however---you are unable to add patients or manipulate the prescriptions and dosages beyond basic changes (the interface will notify you when you attempt to use a feature which is not implemented). All patient data is static and canned, as is all time-based labeling. In the final system, all timestamps would update in real time, and patient statuses would change as you administered (or undid) medication.

Interface Tour

Upon opening our application, the user is presented with a patient overview screen, which displays a list of patients, their locations, and any relevant alerts. A bar across the top displays the name of the application, the name and role (doctor or nurse) of the current user, and a button to add a new patient:

Selecting a patient expands that patient's entry in the list vertically and brings up demographic, medical history, and allergy information in the sidebar on the right:

The patient display consists of three tabs: "Overview," "Prescriptions" and "Administration" if the user is a doctor and two tabs: "Overview" and "Give Medication" for a nurse (the nurse view is not yet implemented). The Overview tab, which is the default, displays the following panels: 

• Vitals, including heart rate and BP
• History of medical actions, including time of prescription and administration of medications
• Current medication schedule, including dosage, frequency, and time of next administration

The Administration tab shows a list of upcoming doses of each prescribed medication, sorted by time to next dose, and a history of all medication given during the patient's stay. Each upcoming dose has a "done" button next to it, which the user can select to indicate that the drug was administered, and an "Undo" link reverses this action:

The Prescriptions tab shows a list of currently prescribed medications along with the dosage, frequency, and start and stop times for each. For each prescription, a pencil icon indicates a button to edit the prescription, and an X button deletes the prescription (not yet implemented):

An "Add prescription" button at the bottom of the list provides text fields for the new medication name and dosage, a dropdown selector for frequency, and datetime pickers for the start and end of the prescription (not yet added). The dropdown frequency selector specifically addresses a common issue we found in user testing, in which users were often confused by the format for medication frequency:
